 flux-core also includes the following services implemented as
-comms modules: _kvs_, a distributed key-value store;  _live_,
-a service that monitors overlay network health and can rewire around
-failed broker instances; _modctl_, a distributed module control service;

 A number of utilities are provided for accessing these services,
 accessible via the `flux` command front-end (see below),
